Benefits of technology

[0012]It is an advantage of the present invention that the mechanism controls the motion of the seat.
[0013]It is another advantage of the present invention that the mechanism not allows rotation of the seat relative to the pedestal base, provide suspension of the seat, and yet minimize cost, weight and static friction.
[0014]It is another advantage that the seat damping mechanism incorporate an air spring allowing the individual to adjust stiffness of the damping mechanism based on individual preference.
[0015]It is another advantage that the mechanism incorporate a mounting means that provides for coaxial orientation of the suspension mechanism and the seat pedestal.

Problems solved by technology

The bushings by themselves, however, have undesirable static friction called “stiction.” Because of this, the suspension systems using only bushings tend to stick and release.
Such systems would be potentially worse for a boat seat as the full weight of a person must be supported compared to a bicycle where typically less than 50% of the weight of a person is suspended on the front suspension assembly.
Any off axis force on a boat seat would cause a higher degree of stiction, rendering a bushing only approach limited in performance.

Embodiment Construction

[0022]FIG. 1 shows a seat 100 attached to a rotation adjustment mechanism 101. A bushing 102 is designed to fit into the rotation adjustment mechanism 101. Inner tube 103 of a telescoping assembly is affixed to bushing 102. When the knob 110A is locked, the rotational adjustment mechanism 101 is firmly fixed to bushing 102, which is affixed to the telescoping assembly. When lever 110B is opened, the seat is free to rotate. A pedestal base assembly 108 consisting of a pedestal tube 104 and base 112 is attached to a boat deck. Outer tube 106 of the telescoping assembly is attached to pedestal tube 104 using a cap 105. Cap 105 is attached by threads to the expansion bushing assembly 107 and outer tube 106 of the telescoping assembly. The purpose of the bushing assembly 107 is to expand so that it can fit pedestal tubes 104 with differing internal dimensions, and in so doing affix firmly to the pedestal tube 104. When cap 105 is rotated by use of a spanner wrench, the expansion bushing ...

Abstract

In a preferred embodiment, a light weight telescoping suspension seat mechanism for a watercraft seat pedestal designed to fit into an existing or new seat pedestal. This suspension seat mechanism contains a combination of roller bearings to allow the seat pedestal to move linearly, but not rotationally. An expanding bushing mechanism secures the seat assembly rigidly to the seat pedestal and floor, and another bushing connects the mechanism to the seat. Each are easily adjusted to allow for easy installation and removal of the suspension seat mechanism. Located inside the telescoping mechanism is a suspension damper with air rebound spring allowing the individual to tailor the suspension stiffness to individual preference. This suspension mechanism provides damping force on the seat. The rebound spring responds to seat movement so as to return the seat to its original position.
